The ecological characteristics of benthic diatom genera from lakes and tarns in mountainous areas of Tasmania (76 lakes) and the South Island (65 lakes) and Stewart Island (6 lakes) of New Zealand were investigated. Community composition and diversity were mainly governed by gradients in calcium, pH and the monovalent/divalent ionic (M/D) ratio, with typical acidophilous and calciphilous communities present in both regions. Highest genus diversity occurred in the pH range between 5.5 and 7.5. Marked interregional differences were present in both calciphilous and acidophilous diatom community assemblages, which were at least partially related to variations in the concentration of the chloride, sodium, potassium and humic substances. Acidophilous communities in New Zealand were typically dominated by Frustulia, Brachysira and Kobayasiella, whereas Eunotia and Actinella dominated in Tasmania. Calciphilous communities in New Zealand were characterised by higher relative abundances of the genera Hantzschia, Diploneis, Nupela, Stauroneis and Synedra, whereas their Tasmanian counterparts were typified by the genera Amphora (subgenus Psammamphora), Biremis, Navicula and Psammothidium. The provinciality of the floras underscores the need for continued protection and conservation of high latitude aquatic ecosystems worldwide and in the Australasian region in particular.

The otocepheid oribatid mite genus Leptotocepheus Balogh, 1961 is recorded in the Australasian region for the first time. The taxonomic status of the genera Leptotocepheus Balogh, 1961 and Longocepheus Balogh & Mahunka,1966 is discussed, resulting in the recognition of Longocepheus as a subgenus (stat. nov.) of Leptotocepheus and the following recombinations: Leptotocepheus (Longocepheus) australis (Balogh & Mahunka, 1966) comb. nov., Leptotocepheus (Longocepheus) globosus (Grobler, 1995) comb. nov., Leptotocepheus (Longocepheus) longus (Balogh, 1961) comb. nov., Leptotocepheus (Longocepheus) youngai (Mahunka, 1984) comb. nov. A new species of Leptotocepheus (Longocepheus) is described from New Zealand, Leptotocepheus (Longocepheus) neozealandicus sp. nov., which differs from other species of the subgenus by the presence of short, slightly developed prodorsal costulae. Revised generic and subgeneric diagnoses, an identification key and distributions for the known taxa of Leptotocepheus are presented.

Particulate Matter Pollution

The International Atomic Energy Agency (IAEA) via the Regional Co-operative Agreement (RCA) has identified air particulate matter pollution as a major transboundary environmental issue in the Australasian region. Sixteen countries in the region spanning from Pakistan to the Philippines and from China to New Zealand are participating in the regional programme "RAS/7/013– Improved information of urban air quality management in the RCA region" that started in 1997. New Zealand is the lead-country for this programme in which nuclear analytical techniques, such as particle induced X-ray emission (PIXE), neutron activation analysis (NAA) and X-ray fluorescence spectrometry (XRF) are used to measure key elements in PM 2.5-0 and PM 10-2.5 filters from GENT stacked samplers collected twice weekly. Major sources of air particulate matter pollution are identified using statistical source apportionment techniques. To identify transboundary air particulate matter pollution events, the data is collated in a large database. Additionally, the data is used by end-users of the participating countries in the programme. An overview is presented.

In this second part of the study of Australasian Forcipomyia, the subgenus Warmkea and the group of subgenera related to Caloforcipomyia are examined. Warmkea is recorded from the Australasian region for the first time, with a single species, albiacies, sp. nov. Four new species of the subgenus Caloforcipomyia are recorded, two – quokkae, sp. nov., and gibbus, sp. nov. – from Australia (the latter also from New Guinea), and pennaticauda from New Guinea, and new records are provided for squamianulipes Tokunaga & Murachi. The subgenus Metaforcipomyia is also recorded for the first time from the region, with five Australian species – tomaculorum, sp. nov.; colonus, sp. nov.; campana, sp. nov.; rupicola, sp. nov.; crepidinis, sp. nov. – and one new New Guinea species, furculae, sp. nov. In addition, the species novaguineae Tokunaga and stigmatipennis Tokunaga are transferred to Metaforcipomyia from the subgenus Forcipomyia. A new subgenus, Bassoforcipomyia, apparently related to the Caloforcipomyia group, is erected for two new southern Australian species, centurio, sp. nov., and incus, sp, nov. The relationships of these subgenera, and the relationships of species within the subgenera, are discussed.

Major Impediment

Glemparon Jaschhof, 2013, a previously monotypic genus confined to Sweden, is shown here to be considerably richer in species, with most species found to occur in the Australasian region. Eighteen new species are described: G. tomelilla sp. nov. (from Sweden); G. aotearoa sp. nov., G. birhojohmi sp. nov., G. cervus sp. nov., G. didhami sp. nov, G. kaikoura sp. nov., G. nativitas sp. nov., G. orautahi sp. nov., G. otago sp. nov., G. pureora sp. nov., G. rakiura sp. nov., G. rotoiti sp. nov., G. rotoroa sp. nov., G. tewaipounamu sp. nov., G. waipapa sp. nov., G. waipoua sp. nov. (all from New Zealand); G. manuka sp. nov. and G. warra sp. nov. (both from Tasmania, Australia). Glemparon sagittifer Jaschhof, 2013 is redescribed. Genitalic illustrations are provided allowing for the effective identification of all the species known thus far. Morphological data obtained here are used for revising the generic definition. Dicerura Kieffer, 1898 is hypothesized as the sister group to Glemparon. The case of Glemparon is discussed as a perfect example of the fact that our collective ignorance of porricondyline diversity in most parts of the world is a major impediment to a better understanding of the European species.
